NET BODY USING SPIRAL WIRES

摘要

A tubular net body using spiral wires capable of being assembled and disassembled on job sites simply and in a short time. A tubular net body using spiral wires excellent in toughness and durability. A tubular net body which uses spiral wires having high toughness and durability, yet capable of being reduced in weight, each spiral wire being formed by coiling a wire having a specified outer diameter into a spiral form that has a spiral diameter almost two times the above outer diameter with its convex portions almost identical to its concave portions, and has specified leads and pitches so that respective concave portions are positioned outside the centers of spirals. The spiral wire is wound in a coil shape to form a horizontal spiral wire. Vertical spiral wires each consisting of the spiral wire are allowed to meet horizontal spiral wires sidewise at specified intervals and fixed to them to thereby form a tubular net body.
